Phosphorus and nitrogen are essential. Phosphorus is vital for the formation of DNA and RNA, which store and transmit genetic information, and for the energy balance of cells. Nitrogen is an essential component of proteins, which are needed for the formation, structure, and function of cells. Without these two elements, no life can develop out of lifeless matter.<\/p>\n<p>A study led by Craig Walton, postdoc at the Center for Origin and Prevalence of Life at ETH Zurich, and ETH professor Maria Sch\u00f6nb\u00e4chler has now shown that there must be sufficient phosphorus and nitrogen present when a planet\u2019s core is formed.

This was exactly the case with Earth around 4.6 billion years ago\u2014a stroke of chemical good fortune in the universe.
